* No Global Census: There's no central organization tracking this information across the globe.
* Variety in Education Systems: Education systems differ dramatically from country to country. Some might have national curriculums, others regional, and some leave more choice to individual schools.
* "American English" is Broad: The term "American English" encompasses many dialects and regional variations. It's not always clear what is meant by "teaching American English."
* Factors Influencing Choice: The reasons for teaching one variety over another are complex and can include:
* Historical Ties: Countries with strong historical links to the U.S. might favor American English.
* Economic Factors: English as a global language is often seen as important for economic advancement, and the U.S.'s global dominance might make American English seem more valuable.
* Cultural Influence: American media, music, and entertainment have a significant influence on many countries, which can lead to a preference for American English.
What We Can Say:
* It's Likely Many Countries: Given the global influence of American English, it's safe to say that many countries around the world teach it, either alongside or instead of their national varieties.
* More Common in Certain Regions: You're likely to find American English more prevalent in countries with close ties to the U.S., such as Canada, Mexico, and many Central and South American nations.
Rather than focusing on a specific number, it's more helpful to consider the broader context:
* English as a Second Language (ESL): In many countries, English is taught as a foreign language, often with an emphasis on a particular variety.
* Variety of English Varieties: While American English is common, other varieties like British English and Australian English are also taught in different parts of the world.
To get a better understanding of how English is taught in a specific country, you'd need to research their national education system and curriculum.
